When using the Packer HCL required plugins stanza getting an error where the 256SUM is not found

[tschilb252]

I was able to implement a workaround pinning at the v0.4.0 or the v0.3.2 version. Still need to fix the root version being whatever the latest release is vs 1.0

packer {
required_plugins {
xenserver = {
version = "= v0.4.0"
source = "github.com/ddelnano/xenserver"
}
}
}

Hey @tschilb252, thanks for making this bug report.

I am able to reproduce the behavior, but I'm surprised since I don't see any releases or tags that match v1.0.0. I ran packer with PACKER_LOG=debug set to see if I could determine where that was being pullet from and saw the following:

So it does appear to be looking for a 1.0.0 release. I checked the releases from URL specified in the logs above (https://api.github.com/repos/ddelnano/packer-plugin-xenserver/git/matching-refs/tags) and found a 1.0 release but nothing that matched 1.0.0.

I took a look at the packer source code and realized that it is padding all releases to 3 digits. So that 1.0 release, which is a tag from before this project was forked, was being transformed into 1.0.0.

I've deleted that tag and verified that issue no longer occurs. Please reopen the issue if you are still experiencing a problem!

Thanks for the prompt response and fix. I was also able to work around the issue with setting the implicit version vs. being lazy and state “this or older”.
